1) In first case, both the objects(hand & tea) are in direct contact, so heat will flow by the process of "Conduction"
2) In this case, objects are not in direct contact, and heat is transferring from one to another by "Convection"
3) Here, there is no contact between the objects (our body & sun), sun light with heat comes through the process of "Radiation"
In short, Your Answers would be:
1) Conduction
2) Convection
3) Radiation
Hope this helps!
Is the velocity constant? Is there any friction?
3 meters per second
then after 40 seconds it must 3*40 = 120 meters
120 meters or 0.12 km if you will
